Thermwell H433FS/3 Satin Silver Seam Binder 1.25x36 in

Product Description

The THERMWELL H433FS/3 is a satin silver fluted seam binder designed to create a clean, finished transition between two floor coverings of equal height. This flat threshold strip measures 1.25 inches wide by 36 inches long and features a fluted profile that adds rigidity while lying flat across the seam. It is commonly installed by flooring contractors, tile setters, and general contractors during finish work on residential and light commercial projects. The satin silver finish provides a neutral, low-profile appearance that blends with a wide range of flooring materials and room finishes.

This seam binder is suited for installations where two adjacent floor coverings meet at the same elevation, such as carpet-to-carpet, vinyl-to-vinyl, or similar same-height transitions in hallways, doorways, and open floor plan areas. The 36-inch length accommodates standard doorway widths and can be trimmed to fit shorter spans as needed. It is sold individually and packaged 24 units per case, making it practical for multi-room or multi-unit projects.
